A gasket is a sealing device made of deformable material usually designed in the form of a ring or sheet.Gaskets create a pressure-tight seam betweenmultiple stationary components, relying on a compression seal to prevent unwanted gas or liquid emissions.
Likewise, o-rings, though similar to gaskets, have a subtly different designation. Unlike gaskets, o-rings are made almost exclusively of synthetic rubberor plastic polymers with elastomeric properties, and are produced solely in ring form.
Gaskets and Orings are commonly produced by cutting from sheet gasket materials, such as gasket paper (beater addition), Non-asbestos, Rubber, EPDM, Nitrile, Buna, Neoprene, Flexible Graphite, Grafoil, Viton, Silicone, Metal, Mica, Felt or a plastic polymer such as PTFE, Peek, Urethane, or Ethylene Propylene (EP).
